TOY GUN.

Specification of Letters Patent.

Patented June 6, 1916.

T 0 all whom it may concern Be it known that I, GEORGE MULLER, a citizenof the United States, and a resident of Newark, in the county of Essexand :4 State of New Jersey, have invented certain g guns in which apieceof paper is broken by the compression of air in a cylinder caused by amovable piston, so that the sud den breaking of the paper produces areport.

The object of my invention is to provide a device of this characterwhich will form an efficient compression of the air in the cylinder andwhich will produce a very loud report when the paper is broken.

Another object of the invention is to produce a toy gun which will bevery easy to operate and one which willbe durable.

Another object of the invention is to provide a gun which may be veryquickly operated.

. Another object is to provide a gun which may be inexpensively stampedfrom sheet metal and which can be assembled with the least possiblesoldering.

In the drawings forming part of this application, Figure 1 is anelevation of a toy gun embodying my invention, Fig. 2 is an elevation ofone end thereof, showing the paper clamped tightly, preparatory tofiring, Fig. 3 is a similar view looking at the opposite side of thegun, Fig. 4 is a longitudinal sectional view, taken on the line H ofFig. 1. Fig.6 is a plan view, and; Fig. 6 is a sectional view, taken onthe line 66 of Fig. 4.

The device consists, primarily, of a cylinder 1 which is preferably madefrom sheet metal, The seam shown in the drawings is preferred as itprevents escape of the air and the interior bore of the cylinder may bemade very symmetrical. This seam, as shown in Fig. 6, is made by turningback the edges 2 of the cylinder and by arranging a separate strip 3having inturned edges 4 over the edges 2 and by pressing the partstogether. There is a piston sliding in this cylinder, which may be ofany desired construction but which is here shown as consisting of a rod5 which extends through an aperture in a cap 6 fixed on the end of thecylinder, and which rod has a handle portion 7 outside the cylinder; ofthe flanges 8 carried by the rod, and of a washer or packing 9 heldbetween the flanges and in close lit with the bore of the cylinder. Thepiston is adapted to compress the air in its upward movement.

In order to form a more airtight seat for the paper there is provided anannular member 10 which is soldered to the top of the cylinder. Thismember has a turned down and rounded portion 11 which forms a seat forthe piece of paper 12, and there is an aperture 13 to permit thecompressed air of the cylinder to pass through and act on the paper.

There is a sleeve member 14: which is revoluble and slidable on thecylinder, and it has a projecting lip 15 which serves as a finger piecefor turning and sliding the sleeve. Preferably, this sleeve does notextend entirely around the cylinder so that its edges 16, 17 may strikeagainst the seam 3 of the cylinder to limit the turning movement of thesleeve in either direction. Projecting from the sleeve are the arms 18which preferably turn out at 19 and then upward at 20 to provide ample.space for the insertion of the paper; and the upper ends of the armsare secured to an annular cup 21 by means of lugs 22 stamped from theedge of the cup and passing through the arms and turned over, as shown.

There is preferably an amplifier or horn member 23, which is secured tothe cup 21 by turning its edge over the edge of the cup as shown at 2 1.The cup 21 forms a socket for a packing 25 which preferably consists ofa washer of rubber or other resilient material.

In order to force the parts tightly against the paper there is providedmeans for 1noving the cup 21 downwardly, simultaneously with the turningof the sleeve. For this purpose there is a ring 26 around the upper endof the cylinder. This ring may be loose on the cylinder, thus avoidingadditional soldering, and it may be prevented moving upwardly by theflange 27 on the top'member 10 and it may be prevented from revolving bythe engagement of its ends 28 against the projecting seam 3 of thecylinder. This ring has cam projections 29 preferably at opposite sidesof the gun, as shown in Figs. 2 and 3. These projections engage, respectively, in a slanting recess 30 in the sleeve 1d and with the edge 17thereof.

Operation: In order to use the device the cylinder is held in one hand,with the sleeve and cup in raised position and a piece of paper isinserted between the member 10 and the washer 25 soas to lie on theformer and cover the aperture therein. The washer is then forceddownwardly to make an airtight connection between the paper and themember 10, so that the air compressed by the piston cannot escape exceptby breaking the paper. This lowering is accomplished by pressing thefinger piece 15 to turn the sleeve to the right in Fig. 1. As the sleeveis thus turned the projections 29 on the ring 26 force the sleevedownwardly and since the cup 21 and washer 25 are carried with thesleeve the washer is compressed upon the paper and upon the member 10and the connection between the paper and the member 10 is completelysealed. The washer 25 is more or less compressed to hold the papertightly and well sealed, regardless of any slight imperfection in thetop surface of the member 10. The piston, having been drawn outwardly,is quickly forced inwardly toward the top of the cylinder, and when thecompression of the air in the cylinder is sufficient to overcome thestrength of the paper the latter is broken and a loud report is madethereby. The sound made by the breaking of the paper passes through thewasher 25, and through the member 23, be-

ing more or less amplified or directed by sufiiciently to remove thepressure of the M washer from the paper. The paper may then be advancedto bring an unbroken portion across the member 10 and the previousoperations are repeated.

Having described my invention, what I claim is:

A device of the class described, comprising a cylinder having aprojecting seam, a piston, an annular member forming a seat, and securedto one end of the cylinder, a ring on said cylinder abutting on saidseat member to prevent it sliding on the cylinder and having its endabutting the seam of the cylinder to prevent its turning, cam portionson said ring, a sleeve revoluble on the cylinder and engaging the camportions ofthe ring whereby the ring will force the sleeve along thecylinder when the sleeve is turned and an annular member carried by saidsleeve and cooperating to clamp a piece of paper on said seat member.

Signed at the city, county and State of New York, this 17th day ofMarch, 1915.
